Based on its experience and capability, The Aveng Group has a significant contribution to make to the future expansion of the power industry in Africa, Australia, Asia, New Zealand and the Pacific Rim.
The Aveng Group has already played a significant role in southern Africa, Africa and Australia’s power generation. The Group has the capacity and capability to deliver extensive large-scale projects.
The Group’s experience spans the spectrum of power generation plants from traditional coal powered to hydro power and wind farms. It has experience in nuclear power, having formed part of the consortium that was awarded the contract for the construction of the Koeberg Nuclear Power Station, the first nuclear power plant in South Africa in 1976.
The Aveng Group has leveraged its vast resources, contributing to the construction of power generation infrastructure, including the combined group-wide skill sets as well as partnerships with external specialist companies. It has the ability to craft packages, which reduce its clients’ risk profiles and resource requirements. With its skills in the structuring and developing project finance deals in particular concession contracts and public private partnerships, the Group is also well placed to add value to its clients in the power sector.
Services include all types of building contracts; a comprehensive portfolio of civil engineering services; maintenance, repair and slipforming of industrial chimneys, stacks and ACC columns; concrete preservation, repair and rehabilitation; mechanical, piping, electrical and instrumentation installations and commissioning; engineering design, draughting and fabrication of structural steel and platework.
The overall scope of works on this design and construct project consists of a 6km long, 5m diameter head race tunnel, two vertical shafts, a 1km long steellined high pressure tunnel, a power station to house twin 70MW generators, and a tailrace outfall into Lake Guy. On completion this was the largest hydro power project constructed in Australia in the past 25 years. The project has been short-listed for the highly acclaimed Australian Contractors Association Project of the Year Award.
Aveng Grinaker-LTA in joint venture was appointed for the civil works package and chimneys construction on the 4 500MW new coal fired power station, which will be one of the largest coal fired, air cooled plants in the world on completion in 2012. The scope of work includes the civil works associated with the main power island and the ancillary structures.
The scope includes operation and maintenance of the coal washing plant and associated infrastructure, from the Run of Mine feeder through to the washed product stockpiles. The plant has been designed for 60 000 tonnes per month ROM feed.
The 166 megawatt Te Mihi geothermal project in New Zealand was awarded to a consortium of partners including McConnell Dowell, SNC-Lavalin and Parsons Brinckerhoff New Zealand in February 2011. McConnell Dowell has been a long time participant in the energy sector, which commenced with the development of the Huntly Power Station in New Zealand in 1977. The company’s energy sector experience includes coal, gas, hydro, geothermal and wind farms. The Te Mihi geothermal project will be completed in 2013.
The project entailed pre-feasibility, feasibility studies and detail design of a large coal beneficiation plant (approximately 14 million tpa), including screening and tertiary crushing, coarse and small coal washing, thickening, filtering, fine coal handling, sampling analysis and product and discard transfer systems. The total plant and associated infrastructure is designed using state-of-the-art 3D software and processes.
Te Apiti is currently the largest wind farm in New Zealand and in the southern hemisphere, consisting of 55 turbines each capable of generating 1,65MW and a total capacity of up to 90MW. McConnell Dowell’s Electrix business unit was engaged to provide electrical services for the project, which included ‘balance of plant’ procurement, installation testing and commissioning of 4,5km of 110kV transmission line, 48km underground cabling and a 110/22kV, 100MVA substation. The wind farm started generating electricity into the National Grid during July 2004.
